Wolf Gallery
Encrypted, offline photo & video vault with a comfortable gallery
New in version 1.3.8
Wolf Gallery can now be moved both ways between your device's internal storage and an SD card, from Android's app storage settings. It moves even with your photos and videos already inside — everything comes along, including your albums and settings, and nothing is deleted or reset. The vault stays encrypted the whole time, and nothing is ever written out in the clear.

Wolf Gallery is an offline gallery that keeps your photos and videos encrypted on the device.
Each file is stored as ciphertext in the app's private storage, so other apps and the system only ever see encrypted data. Files are decrypted on demand, including when you share to another app or set a wallpaper, so your media is never written out in the clear. You can use it as your main gallery or keep it next to the stock one as a private vault.
Development is active and ongoing.
Security
Every file is encrypted in an isolated vault inside the app's private storage. There is no internet permission and no accounts, cloud, telemetry or trackers, so the app simply cannot reach the network. Encryption uses authenticated AES-256-GCM, so any tampering is detected on decryption, and keys are derived from your passphrase with Argon2id, the memory-hard winner of the Password Hashing Competition. Your passphrase is never stored. The vault key is wrapped with an Argon2id key on top of the hardware-backed Android Keystore, so both the device and your password or PIN are needed to decrypt. The vault is symmetric-only, which makes it quantum-resistant by design, and a native crypto core zeroes key material in memory after use. Screenshots and Recents previews are blocked, wrong unlock attempts are slowed by exponential backoff, and an optional wipe after a set number of failures is available. A built-in self-test screen runs the crypto, file-format and migration checks right on your device.
Organize
Create groups and albums inside the app and rename anything, including with emoji. Sort, search and pin your groups, albums and files, set an album cover from any picture with adjustable framing, and import or export on your own terms. You can share to other apps or set a wallpaper directly from the vault.
Appearance
Choose from several themes, including pure-black dark modes, paired with a custom accent color. Adjust the grid density, switch thumbnails and albums between rounded and square corners, and place the action bar at the top or the bottom to suit your grip.
Other
A built-in trash keeps deletions undoable, a first-run wizard makes setup effortless, and the app is available in several languages with more translations on the way.

New in version 1.3.7
Added three Material 3 themes: light, dark and black for AMOLED screens. Each can be paired with an accent colour of your choice, and the whole interface follows it.
Added sharing into Wolf Gallery. Photos and videos can now be sent from other apps straight into the vault. They are accepted only while the vault is unlocked, and nothing is imported if it is locked or the app is fully closed.
Fixed a visual glitch in the navigation bar.
